SKF · Seals & Gaskets · Hydraulic Guide Rings & Strips
SKF PGR50X45X7-PF hydraulic guide ring / wear ring / bearing strip. Non-sealing polymer guide ring that carries the side load in a hydraulic cylinder, preventing metal-to-metal contact between rod-piston-tube. Materials cover PTFE with bronze filler, glass-filled thermoplastic and acetal. Available as straight-cut or angle-cut strip; standard groove per ISO 10766. Designation follows the SKF alphanumeric identification convention where the numeric block encodes the boundary plan and the suffix declares execution options (material, sealing, cage, precision, clearance, lubricant). Genuine SKF supply carries the SKF logo etch or moulded mark and hologram-authenticated packaging.
